Chemical cleaning of heat exchangerscould be a tedious and time-consuming process, costing a good amount of money, though it is important to ensure the condition of the equipment in its best condition. The presence of high temperatures works towards the detriment of the equipment and machinery, especially when there are fluctuations in temperature. And it is only with proper cleaning that the equipment and machinery could be kept clean.
It is quite a tedious task to keel heat exchanger tubes cleaned due to the structure or arrangement of the tubes, which make the cleaning process a tough job due to the problem of access and cleaning. Hence, the traditional methods of cleaning, like water blasting through tubes, and in certain cases, there is quick re-fouling due to the impossibility of removing all the debris. Tubes that are not straight and are bent or coiled make water blasting through them an impossibility for cleaning, as water flows in a single direction, and while it moves in a curve way within the tubes, the water slows down, and there is deposition of the fouling materials in specific areas. Hence, in the traditional cleaning methods, the contaminants again start accumulating after a passage of initial cleaning.
Constant cleaning is also not the solution due to the fact that in certain cases, there could be instances of heat exchanger tubes failing to operate for it cleaning, and with stoppage of its working, there are no chances of the machinery to operate, for apparent reasons. And it goes without saying that facing downtime in equipment operation can only increase the problem further.
One good solution when it comes to cleaning heat exchanger tubes is to use some new equipment that is designed mainly to help in the cleaning process of this type of equipment. One will come across physical cleaners like scarping tools and abrasive balls while using detergents or acids as chemical cleaners along with a powerful combination of both chemical and physical cleaners along with hydro blast. Users need to ensure the compatibility of cleaners and heat exchanger tubes before the beginning of cleaning. For example, certain acids react with some metals in a negative manner, and hence, it is important to check with the hardware store who wishes to use the chemicals, before using the acids.
Finally, it should be noted that no cleaner is effective if the regimen doing the cleaning is lax in approach. Hence, it is important to keep all these important pieces of information to keep yours in the best working condition.
With proper knowledge, heat exchanger tube cleaning could be done by anyone, if they have the basic knowledge of doing it. For those who prefer the do-it-yourself option would not find any difficulty in doing the task. A good number of methods are available for cleaning exchanger tubes. The other is making use of high-pressure water system. The last method is to use brushes, scrapers and abrasive balls as part of mechanical cleaning. All these are the most opted methods to clean tubes. To extend the life of the full unit, it is important to go for regular cleaning of the exchanger tubes. This would make the unit work to its fullest efficiency.
Nowadays, heat exchanger system is often seen in heat swimming pools. One can save money while making the system work in top working condition through cleaning the own heat exchanger tubes. It would be best to go for cleaning exchanger tube cleaning after few months. At the minimum, one should inspect to find out if there is a need for cleaning. If no cleaning is required, then it would do well to clean it fully twice a year. For proper cleaning of the exchanger tubes, it is necessary to remove them from the system. Any loose items should be removed that is near the tube ends and within the well. One should make use of a brush and push it along the tube for starting the cleaning process. There must be strong nylon bristles in the brush. This works towards loosening and removing whatever loose materials exist within.
As he brushing process goes on, it will be found that some material exists within the sidewall of the exchanger tube. The use of a metal or plastic scraper will help in removing any material stuck within the wall of the tube. You should be careful about not damaging the wall of the tube. Ensure the scraper is not harder compared to the substance of the wall of the tube. See to it that the wall of the exchanger tubes are not scratched as that could lead to malfunctioning of the tube and as there are possibilities of particles sticking to the wall of the tube. Hence, the use of a plastic scraper is recommended.
Lastly, to clean heat exchanger tubes, one can use water jet that needs to be forced through the tube to remove loose particles that remained with the previous attempts. If calcium deposits remain on walls of the tube, then one should use chemicals to get rid of them. Now that you are aware of the basic information for chemical cleaning of heat exchangers, you could collect more information before dealing with this type of task.
